Our research

Software Component Retrieve and Reuse: Efficient and Effective reuse of existing software is a key issue to improve productivity of software system. We propose a novel approach for ranking and retrieving software components.
Code Clone: A code clone is a code portion in source files that is identical or similar to another. Clones make the source files very hard to modify consistently. We have depeloped a clone detection algorithum and tools named CCFinder and Gemini.
Program Dependence Analysis: Software systems are getting larger and more complex. Huge program is very difficult to find faults, without any supports of some tools. We study Program Dependence Analysis that applied to program debugging and maintenance.
